PORTHOLE TO LOUVER CONVERTER Filed April 6, 1949 Patented July 24, 1951 UNITED 2 Claims. 1 I? T This invention relates to a porthole ejector head and more particularly to a means for secur ing. the head to'an open porthole. The device is particularly well adapted for use with a 'porthole fitted'with an interior hose connection,such ,as' the ventilating portholesin the side walls of automobile. fenders which are hose connected to the automobile engine chamber. The installation of the invention on an automobile porthole tends to reduce wind resistance, to intensify vacuum at the chamber end of the hoseland thereby to create a better air flow through the porthole; to reduce the possibility of foreign matter enteririgthe porthole; to hide the opening and thereby remove the temptation for pranksters to stufi the portholes with rags, paper orother refuse, and to improve the appearance of the vehicle. An important object of the invention is to provide a device which can be installed in a porthole without access being had to the interior side of the porthole carrying wall. A further important object is to-provide a device whichcan' be installed in'a hose connected porthole without -removing the connecting hose. Further obj ts of the invention are to provide a device whichcan STATES A NT T' 'F' PORTHOLE TQLOUVERId M Kline,lndianapolig fllid I AplzlicationAl i lfi 9 Sa -M I i .9 2 I V ..i v Q,

A head I is formed to fit snugly over the outer rim 2|.

The head Iilis' formed to comprise essentially the] collar 25. to jfit'snuglyover the outside of the rim'21Iasa centering means, and a hood 23 raised from this"colla r 25' to provide an open window 21, across'the' rear side. The'hood slopes from the collar 25ffrom a forward point 28 and arcuate. lines 29' and 35 upwardly therefrom in the nature ofa louver; opening from the rear side only. The "rear edge 36 of the hood 26 extends in spaced'relation outwardly from a substantially planar apron 31 which" is turned from the col- A spring-H is provided to have a short arm I2 and along arm' I3 extending from a short intervening length8i Hook portions I l and I5 extend laterally outwardly in opposite directions iromthe ends of-'arms--=I2 and I3 respectively. As indicated inF igs. 2, 4 and 5,'the arm I2 is turnedat right angles from the length 8, and the be installed with'no-special tools; which can Joe installed in a matter of minutes; and which can be installed by an ordinary automobile mechanicwithout special training.

These and many other objects and advantages of the invention includin the unique and simplified parts forming the structure and assembly thereof will become apparent to those versed in the art from the following description of one particular form of the invention as illustrated in the accompanying drawin in which Fig. 1 is a view in side elevation of a structure embodying the invention as applied to an automobile venting porthole;

Fig. 2 is a bottom plan view of the structure;

Fig. 3 is a view in rear elevation of the structure;

Fig. 4 is a view in horizontal section on the line 4-4 in Fig. 1; and

Fig. 5 is a view in section on the line 5-5 in Fig. 4.

Referring to the drawing in which similar numerals indicate similar parts throughout the several views, the porthole 20 shown in Figs. 1, 4 and 5, is defined by a cylindrical inner sleeve 22, from which there extends externally an annular outer rim 2|. A rubber connecting hose 23 telescopes by an end over the sleeve 22. The rim 2| is fixed by any suitable means such as by screw 9 to a wall 24 to have the hose extend inwardly therefrom.

arm 13" extends in a diagonal direction, relatively downwardly and awayiromsaid arm I2. A selfthreading screw "It passes freely through the apron= 3l of the head I'll to screw-threadedly engage through the-spring length 8. The hook portions I4 and I5 are of sufficient length to extend over the edge I! of the shell 22 and engage the hose 23, but said hook portions I4 and I5 should not be long enough to pierce the hose 23. The side edges 30, 3|, 32, and 33 of the hook portions I I and I5 respectively are flat and normal to the faces of the hooks I4 and I5 in order to prevent circumferential movement of those hook portions after they have become embedded in the hose 23, as will be presently described.

The shape of the spring II is made to position the length 8 adjacent one side of the shell 22 to havethe arm I2 extend inwardly therealong in close proximity, and to have the arm I3 extend diagonally across the shell toward its inner terminal end IT. The outer ends of the hook portions I4 and I5 are spaced apart a distance ex ceeding the internal diameter of the shell 22, whereby they must be retracted one toward the other to insert the spring II within the shell 22.

To install the structure, the self-tightening screw I6 is started in the spring II. The spring arms I2 and. I3 are then compressed and inserted through the porthole 20, into the sleeve 22, with the longitudinal axis of the spring at a right angle to the desired final position of the louver opening 21 and with the hook portion I4 of the shorter arm I2 pointing in the direction the louver opening 21 is to face. After insertion, the entire device is pushed inwardly until the hook portions [4 and I5 snap over the edge II of the porthole inner rim 22. The screw 16 is then tightened until the louver head I0 is snugly secured over the porthole 20. The structure is normally installed on a vehicle with the louver head opening 2'! facing the rear of the vehicle, as in this position the streamlined shape of the vehicle is preserved and the ejecting action of the head [0 is secured when the automobile is under way.

While I have herein shown and described my invention in one particular form it is obvious that structural changes may be made without departing from the spirit of the invention, such as in the position of the screw on the louver head, the number and shape of the spring arms, and the various proportions of the parts, and therefore I do not desire to be limited to that precise form beyond the limitations which may be imposed by the following claims.

I claim:

1. For mounting over a porthole presented as an opening in the end of a cylindrical sleeve having an externally presented surrounding rim, and a resilient hose telescoped over and extending from the sleeve, an ejector head formed to seat snugly over said rim to center the head; a hood rising from one side of the head to terminate beyond the mid-portion of the head and short of the other side; a planar surface extending beyond the termination of the hood; a screw revolubly extending through said surface; a leaf spring having a length substantially parallel to said surface and screw-threadedly receiving said screw therethrough; a leg of said spring extending from one end of said spring length parallel and in close proximity to the wall of said sleeve; a foot on the end of said leg outturned to engage under the end of said sleeve; a second leg of said spring extending diagonally from the other end of said spring length and from said head within said sleeve; and a foot on said second leg outturned to engage under the end of said first leg; the distance from outside to outside 4 of said feet being normally greater than the internal diameter of the sleeve.

2. For mounting over a porthole presented as an opening in the end of a cylindrical sleeve having an externally presented surrounding rim, and a resilient hose telescoped over and extending from the sleeve, an ejector head formed to seat snugly over said rim to center the head; a hood rising from one side of the head to terminate beyond the mid-portion of the head and short of the other side; a planar surface extending beyond the termination of the hood; a screw revolubly extending through said surface; a leaf spring having a length substantially parallel to said surface and'screw-threadedly receiving said screw therethrough; a leg of said spring extending from one end of said spring length parallel and in close proximity to the wall of said sleeve; a foot on the end of said leg outturned to engage under the end of said sleeve; a second leg of said spring extending diagonally from the other end of said spring length and from said head within said sleeve; and a foot on said second leg outturned to engage under the end of said sleeve diametrically across from the foot of said first leg; the distance from outside to outside of said feet being normally greater than the internal diameter of the sleeve; said spring being rectilinear in cross-section, and said feet having corners engaging said hose to prevent slippage of said feet circumferentially of the sleeve.
